1 Red or black colored stool may be a sign of bleeding in the GI tract (from the esophagus, stomach, small intestine or colon) and should not be ignored.  When stool color changes, what tests need to be done depend upon depends upon what cause is suspected for the stool color change.
Black stool in no way means that you have hemorrhoid bleeding since hemorrhoidal bleeding is vibrant red. Dark poop means that the bleeding is not in the large bowels or rectum and is not occurring because of diverticulitis, a condition that develops in the colon and manifests itself with red, bloody stool.
